@joxean You mean the power lines/transformers? If so, are these expensive enough to outweigh differences in power plant rebuilding costs? I mean even if you rebuild the distribution system you'd still be in trouble if there's nothing to hook up to, but maybe the distribution is much more costly than the plant so it doesn't matter? On the other hand, how many men, bombs, planes, etc. do you need to wipe a distributed vs. monolithic system?
